If I'm a 20 year old college student who can play ball, you best believe I want to see what I am worth by entering the portal. This NIL money is big money when you are 20 (and for top players, it is big money period) and I think the siren song of quick cash would be difficult to ignore.
However, I would also think that these guys who go portaling multiple times are missing out of the depth and quality of relationship you make in college and with your coaching staff. How can you progress through a college education and get a quality degree when you are playing at 3-4 different school? How do associate yourself as an alumni if you were never anywhere for more than a year or two?
It is a mess, everyone knows it is a mess, at some point, it will be addressed in some type of equitable way so college athletes can get some type of compensation without having to prostrate themselves in this bidding war of the portal every year. But that time is not right now. Just an unregulated clown show right now.
